WINDOW-SCREEN AND VENTILATO R.

SPECIFICATION forming part of Letters Patent No. 324,077, dated August 11, 1885.

Application filed March 23, 1885.

To all whom it may concern:

Be it known that I, JOHN G. BRoNsoN, of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved VVindow-Screenand Ventilator, of which the following is a full, clear, and exact description.

The object of my invention is to facilitate the ventilating of rooms, (so.

The invention consists in the combination, with a sash, of a vertically-sliding screen below the sash and a vertically-sliding deflector a short distance to the inside from the sash,

which screen and deflector fit in pockets on the sill, which pockets can be closed by sliding coverstrips.

Reference is to behad to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a cross-sectional elevation of part of a window provided with my improved screen and deflector, Fig. 2 is an inside view of-the same, parts being broken out. Fig. 3

is an enlarged detail sectional view of one end of one of the covering-strips.

From the upper surface of the inner window-sill A a recess or pocket, B, extends downward vertically and extends from one jamb, C, to the other, and is adapted to receive the deflector D, which is adapted to slide down into the pocket or recess B. A sliding bar, G, has its ends passed into horizontal grooves E in the jambs C, directly above the sill A, and is arranged to slide toward and from the bottom stop-bead, F, and to cover the top of the recess B. The deflector preferably cousists of a wooden frame in which one or more panes of glass are held.

Below the lower sash, H, a recess or pocket, J, is formed in the sill, and extends from end to end, and serves to receive avertically-sliding screenframe, K, in which two wire nettings, L, are secured one at the front or outer side and the other at the back or inner side.

In each jamb C a groove, M, is arranged for receiving tongues N, secured to and projecting from the ends of a rail, bar, or strip, 0, resting on the sill and adapted to slide on the same toward and from the bottom stop-bead, F, and which strip 0 serves to cover the re- (No model.)

cess J. The grooves M are slightly inclined downward and outward from the bottom stopbead, F, as shown. The deflector D and the screen-frame Kare arranged to slide in vertical grooves on the jambs or between vertical guide-strips on thejambs.

The sash H is raised, the strip 0 pushed to the outside, the screen-frame K raised out of the pocket J, the strip 0 is pulled inward to cover and close the pocket J, the screen-frame is lowered upon the strip 0, and the sash H is lowered upon the frame K. Fresh air can now pass through the apertures in the screens.

To prevent the cool, fresh air from striking the heads or bodies of the occupants of the room, and to cause it to displace the warm air in the upper part of the room, there is provided the deflector D, which is raised out of its pocket and rested onthe covering-strip G. The fresh, cool air strikes the deflector and is guided upward by the same, as indicated by the arrows.

When the device is not in use, it is entirely out of the way in the pockets B and J'. The device can be applied on any window. 7

So that the rain cannot work through the joint between the inner edge of the strip 0 and'the bead F,a recess is formed in the front of the head, into which recess the inner edge ofthe strip 0 is passed, as shown in Fig. 1, thus forming a tight joint. So that the rain will not pass from the ends of the strip 0 into the grooves M, the outer ends of the tongues N are inclined upward, and the grooves M are also inclined from their inner ends to the sides of the frame, so that any rain that may find its way into them can runout very easily. The tongues N extend across the entire width ofthe strip 0.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with a sill having a pocket below the sash and a pocket a short distance to the inside from the sash, of a vertically-sliding screen below the sash and a vertically-sliding deflector, substantially as herein shown and described.

2. The combination, with a sill having a pocket below the sash and a pocket a short distance to the inside from the sash, of a vertically-sliding screen below the sash, a vertiing the horizontal grooves E and the horizoncally-sliding deflector, and of strips for closing the tops of the pockets. substantially as herein shown and described.

3. The combination, with the sill having the pocketsBJ, and thejambs C,having thegrooves E and M, of the sliding screen K, the sliding deflector D, and the sliding stripsG O, guided by the grooves E and M, substantially as herein shown and described.

4. A ventilator and deflector comprising the sill having pockets B J, the jambs O, havtal inclined grooves M, the sliding strip G, the sliding strip 0, having its ends inclined to fit the inclined grooves M, as described, the vertically-sliding screen K, Working in the pocket J, and the vertically-sliding deflector D for the pocket B, substantially as set forth.
